Power Computing when a Power Computing Mac Clone was faster and more robust than what Apple offered.
Power Computing was ahead of its time.
Instead of learning "address multiple price points and be agile with updates", Apple learned "hold your tech stack closely and make mostly premium products".
Power Computing would sell you a top-end Mac at a competitive price point and update their offerings regularly.
Apple sells you a Mac Pro that's trounced by AMD offerings that sell at half of Apple's starting price. Or an iMac Pro that's been ignored for 2 years. Or a keyboard that didn't work for 4 years. Or a MacBook Air without a Retina display for nearly 5 years. Or an $1100 phone with a notch. Or a $700 phone from 2 years ago based on a design from 6 years ago. Etc.
